PurpleFlare Posted May 26, 2011 Posted May 26, 2011 Yesterday I combined 6 Potassium nitrate, 4 sugar, and 1 aluminum powder then put it in a tube and add fuse to it. I tried to light it, but it didnt do a thing. Today I went to retrieve it and open it to see if it was fuse that was the problem. To my surprise, inside was all charred! What could have caused this? How do I fix this problem?
dagabu Posted May 26, 2011 Posted May 26, 2011 Sounds like it smouldered over time. What do you WANT it to do? -dag
PurpleFlare Posted May 26, 2011 Author Posted May 26, 2011 (edited) Yeah. I was hoping that it'd emit sparkles and give off pinkish purplish flame. I was trying to make a fountain. Edited May 26, 2011 by PurpleFlare
Mumbles Posted May 26, 2011 Posted May 26, 2011 I've already given you a website with plenty of formulas, which are tried and true. Why not try one of them instead of wasting your time trying to make your own up? I don't know how fine your aluminum is, but for fountains somewhat coarser is better. Also, most fountains require a clay nozzle or choke.
dan999ification Posted May 28, 2011 Posted May 28, 2011 i think the sugar slowed the burn down and all the metal stuck to it even sugar rocket fuel doesnt really make a long flame good for fountains, you cant make coloured flames with kno3 just pinkish and orangemake one of these you wont be dissapointed mine was quite scary really with 6-8ft flame and sparks every time it spat i thought it was going to blow next time i would add 8-10% metal and maybe make the nozzle a tad bigger you can do this in 15 minutes but youll need some charcoal. made by nhilhttp://youtu.be/13vMBniEhx8made by medan
